Chapter 3. Auto Cost
auto-cost reference-bandwidth bandwidth
Syntax Description:
bandwidth—. Value to use as the reference bandwidth when calculating the cost of an OSPF route. Range of values is 1 to 4,294,967 Mbps. The default value is 100 Mbps.
Purpose: By default, OSPF calculates the cost of an interface by dividing the bandwidth of the interface into 100,000,000. Table 3-1 lists the costs for various interface types. Using the default value when your network has interfaces with a bandwidth greater than 100,000,000 is not recommended. OSPF will not be able to differentiate between a 100-Mbps interface and any interface with a bandwidth greater than 100 Mbps. This command allows you to change the OSPF reference value globally so the calculated ...
